Adobe LR and my mac is uppdated
This happend when I read from Lexar CF (sometimes) RAW files from Canon eos 1DX.
When I click on the images so they look normal.
Why is it happend?
Mac mini I7, 16 MB
Those are corrupted files. 99% of the time it is a hardware problem:
bad memory card
bad card reader
broken USB cable (common)
USB port having problems
bad sector(s) on your hard drive
If you have the options available, try copying the images from the card again using a different hardware combination from what you used previously.
